Abstract

The invention discloses a high-efficiency heat preservation foam plastic, belonging to the technical field of foam plastic preparation. According to the method, titanium nickel yellow, rock wool, vitrified microbeads and the like are taken as raw materials, and are subjected to ball milling impregnation and high-temperature heat treatment to prepare heat treatment materials; in the process that the titanium nickel yellow is sintered and adsorbed on the surface of the vitrified microbeads, the formed system can enable light to be reflected and scattered for many times, so that light energy canbe well absorbed and a heat preservation effect is provided; and in the process of preparing urea-formaldehyde resin, modified materials are added to modify the urea-formaldehyde resin, so that internal tensile force and heat preservation effect are improved. According to the method, alum, manganese iron ore and smithsonite are taken as raw materials, so that metal cations are fully complexed andgradually polymerized to generate reticular polyethylene glycol, the heat preservation effect is improved, and the heat dissipation rate is reduced. The method solves the problem of poor heat preservation performance of the commonly used foam plastics at present.

Description

technical field [0001] The invention belongs to the technical field of foam plastic preparation, and in particular relates to a high-efficiency thermal insulation foam plastic. Background technique [0002] Plastic is a very important organic synthetic polymer material with a wide range of applications. Plastics are formulated from many materials, among which high molecular polymers, also known as synthetic resins, are the main components of plastics. In addition, in order to improve the performance of plastics, various auxiliary materials must be added to high molecular compounds, such as fillers, extenders, etc. Plasticizers, lubricants, stabilizers, colorants, antistatic agents, etc., can become plastics with good performance. As an important material for the preparation of plastic products, compared with pure plastics, foamed plastics have the advantages of low density, light weight, and high contrast strength; they have the ability to absorb impact loads; they have exc...
